GREENWICH — People hungry for a taste of McDonald’s food were surprised this past week when they found the restaurant encircled by chain link and a sign saying it was closed for repairs.

It will be weeks before it reopens, a corporate spokeswoman said. And when it does, there will be some big changes.

“When the restaurant reopens this fall, guests will notice a modern look and feel with new designs and new ways of ordering with self-order kiosks,” said Amanda Pisano, a brand reputation manager for McDonald’s New York metro region. “Additionally, guests’ orders will be delivered to tables by crew members, allowing customers to relax and enjoy a more custom dining experience.”

The restaurant officially closed for the renovations in the evening of Aug. 13 with only a hand-typed sign on the doors acting as notice.

The Riverside renovations come after similar upgrades to the McDonald’s in downtown Stamford on Bedford Street. That restaurant, which was closed from April to August, now offers kiosks for self-ordering and a table service option.

While Connecticut, as part of the New York metro region, is one of the first places to see the changes, it will not be the last. Pisano said it is the goal of company CEO Steve Easterbrook to have most United States McDonald’s modernized by the end of 2020.

“The changes under way at the Riverside restaurant are reflective of a new restaurant model that has been successfully rolled out in more than 2,600 international McDonald’s restaurants and puts more choice and control in the hands of guests by evolving how they order, what they order, how they pay and how they are served,” Pisano said.
